Operating noise of the machine
is dramatically reduced
The strokes of the right and
left thread take-up are
separately adjustable
The adjustment range of the
needle thread tension is widened
●
The operating noise produced by the
hook and thread take-up lever is
substantially reduced.
With its decreased noise level and
improved sound quality, the machine
offers a comfortable work environment
that reduces operator fatigue.
●
The improved opener reduces the
impact against the bobbin. By reducing
variations of bobbin thread tension
caused by the opener, irregular stitches
are eliminated.
The machine has two thread take-up guides,
one for the right thread and the other for the
left thread. As a result, the strokes of the
right and left thread take-ups are separately
adjustable. When the right and left portions
of the material differ in thickness, the
strokes of the thread take-up can be
accurately adjusted for the right and left
threads. With this capability, the machine
delivers consistently improved seam quality.
●
The needle tension controller has been
changed to the 1-needle, lockstitch type.
The style of the thread take-up spring
has been modified not only to allow the
spring to work more effectively, but also
to widen the needle thread adjustment
range compared with that possible with
the conventional thread take-up spring.
The thread tension can be easily
adjusted when changing the material to
be sewn. In addition, the thread tension
is further stabilized even when sewing
under a lower thread tension.
●
To downsize the design, the thread take-
up spring is integrated with the tension-
regulating knob. As a result, these parts
project out less from the machine, opening
up a clearer view of the area around the
needle entry for easier operation. In
addition, the machine offers easier
threading of the needle as compared with
the conventional machine head.
●
One available model is equipped with a newly developed a hook
that uses a non-rotational bobbin for the vertical-axis hook. For
the hook with a non-rotational bobbin, the bobbin is secured in
the bobbin case and does not rotate as the bobbin thread feeds.
This prevents variations in thread tension caused by changes in
the amount of remaining bobbin thread and idling of the bobbin.
With this hook and bobbin, the machine is able to use the full
amount of bobbin thread and sew consistent with a lower thread
tension compared with that used with the conventional hook.
●
The machine type provided with a latch hook is also available.
Select the type that fits your purpose.
(The latch hook is exclusively designed for the LH-3126F.
However, the conventional bobbin can be used with the latch
hook.)
